i RESILIENT VEHICLE-WHEEL.

Specification of Letters Patent.

Patented May 2, 31916.

Application led une 23, 1915. Serial No. 35,746.

improved yresilient or spring resisted vehicle wheel having its parts so arranged and `adjusted as to provide the requisite elasticity, kand stability and at the same time eliminate the various objectionable features frequently found in vehicle wheels ofthis class.

A further object rof the invention is to improve the construction of the movable spoke members and provide the proper form of connections or bearings between the wheel-hub and felly members whereby to brace the wheel as a whole as againstlateral stresses at the hub and felly and at the saine time provide for the requisite movements of the hubhand felly members toward and from each other as in passing obstructions, taking up vertical shocks and vibrations, and ythe like.

A still further object of the i invention kis to provide improved spoke members adapted for use either assuspension or compression spokes, or as combined suspension, and compression spokes, andy provided with improved spring members adapted to' control or regulate the sensitiveness of thef wheel yfelly with respect .to superposed loads Vand the impact' due to passing obstructions to meet thevaiying demands of actual service. With the above mentioned 'and other'ends in view, the invention consists in the novel construction7 arrangement, and combination of parts, hereinaftery described, illustrated in `some of its embodimentsm thev accompanying drawings, andiparticularly pointed out in the appended claims.

Referring to the drawings forming a part of this specification, Figure l, is a side elle vation of a resilient wheel of the suspension type constructedin accordance with this invention, a portion of one of the disk shields or casings being brokenaway for the purpose of clearer illustration of the parts.

Fig 8, aside elevation under ertreme load or depression, with the toggle klink spoke springs and one of the lshields removed, the toggle spokes being shown in kproper relative position. Fig. 4, a segmental side elevation of the hub and felly portions of a modification embodying a` combined. suspension and compression wheel.

Fig. S, across secprisesy a hub member l, provided with side bearing disks la, the latter being provided at suitable intervals with bolt or rivet receiving openings 1b. y

As a means for resiliently connecting and supporting the hub and felly members l and 2, respectively, as well as providingl means whereby said hub and felly members l and 2, may be moved toward and from eachy otherk and also supporting the latter as" againstzlateral stresses or displacement, a plurality of toggle link spoke members 3, are provided, said spoke members being made up of toggle links arranged in pairs and being connected at their inner or knuckle endsvby means of bearing members l, thlefouter ends of the toggle link spoke, members being arranged between and connected to circumfei'entially arrangedk felly spoke bearing flanges 2f, by means of transversely extending bearing members 4a.

`If desired, the inner or knuckle ends of the toggle links 3, maybe held in spaced relation to each other by means of spacing fr or separating springs 5, (see. Fig. 2) surrounding the bearing members e-, or preferably by means of male and female bearing portions 3a, and 3b, respectively,` as shown `mostclearly in Fig. 5 .of the drawings. lf desired,`the toggle links may be arranged in pairs and spaced from each other by fmeanskof an integral webk portion 3C, as shown most clearly in Fig. Y

ings;

ofk the draw,u

As a means ot resiliently connecting the outer or hub and telly bearing portions ot the toggle link spokes to each other, as well as resiliently connecting the hub and telly members ot the wheel to each otheigcoiled suspension springs 6, are provided, said springs 6, being preferably connected to the bearing members 4a, `through the medium ot spring bearing members 7, the latter being preterably provided with Vspring attaching lugs 7a, provided with spirally arranged grooves 7b, radapted to receive and contain theV adjacent convolutions ot the springs 6. The spring bearing members 7 also act as spacing members to holdthe hub and telly bearing ends kot the links 3, in proper spaced relation to veach other as well as provide a proper bearing surtace tor the adjacent or contiguous parts. v

It it is desired to transform therwheel into a combined suspension and compression wheel, or in other words, lessen the sensiltiveness ot the toggle link spokes to carry an increased load, the inner or knuckle ends ot the toggle links may be turther braced byV means ot compression springs 8, intervas posed between the wheel telly 2, andthe knuckle portions ot the links by means ot a bearing member 8a, at one end and a second bearing member 8b, at the other as shown most clearly in Fig. 4 ot .the drawings.

It will be observed that the toggle links 3, forming the spoke members are arranged in transversely extending pairs and that the 'bearingv disks or flanges la, ot the hub member, and the telly flanges 2, ot the telly, term channeled hub and telly members to receive and contain the respectivepivoted ends ot the toggle link spokemembers and c that the latter are arranged within and abut against the inner sides ot the lianges la and 2a, thereby maintaining the parts in alinement whereby to brace the wheel as a whole as against lateral stresses at the hub and telly. Y

It desired, the spoke andspring members may be shielded by means ot disk shields 9,

secured to the wheel telly 2, by means ot vvenient torm.

From the toregoing description, taken in connection: Vwith vthe accompanying drawings,the operation and advantages ot our invention willbe kreadily understood.V

Having thus described some ot the embodiments ot our invention, what we claim and desire to secure by Letters Patent, is,-

1. In a resilient wheel, the combination with circumterentially channeled hub and telly. members; ot toggle link spoke mem-V bers arranged in pairs and spaced' trom each other by means lot an integral web portion, said spoke members being pivotally mounted within the channeled portions ot said hub and telly members, spring connecting bearing members pivoted between saidspoke members, spring 'connecting and spoke spacing members mounted in and connected to the pivoted portions ot said toggle link spoke members, suspension springs con* nected to said spring connecting and spoke spacing members at the hub and telly portions ot said wheel, and compression springs interposed between said bearing members at the knuckle portions ot said togglelink spoke members and said telly member.

V2. A resilient wheel., comprising kchanneled hubl and telly members, toggle link spoke ymembers arranged in transversely eX- tending pairsand connected and spaced trom each other by meansot integral web portions, said toggle link spoke members havf ing their outer ends pivoted within the ychanneled portionsotsaid hub and telly members, pivoted ybearingand spacing members between the pivoted outer and knuckle ,portions ot said spoke members, and means connected to andinterposedl between ,said rbearing and spacing members tor resiliently resisting the movements oty said hub and tellyv bearingV portions and the knuckle .portions ot said toggle link spoke members.,y

3. A resilient wheel, comprising'hub and telly members provided withk spoke bearing y flanges extending toward veach other, toggle link spoke members including integral web portions arranged in transversely extending pairs and pivotally mounted and interposed between said spoke bearing flanges, bearing members interposed between the pivoted portions ot said t'ogglelinks at the hub and telly portions ot said wheel, bearing pins extending through the latter, spring kconnecting and spokeV spacing bearing members interposed between the knuckleportions ot otv said toggle'link spoke members, and tension and c compressionV springs connected to.

and interposed between said' bearing members ot said hub and telly members, and said knuckle portions ot said togglelink spoke members and said telly member, respectively. j

' 4f. A resilient wheel, comprising lchanneled hub and telly members, toggle link spoke members arranged in transverse pairs within and between said channeled hubv and telly members, Vspacing members between the knuckle ends ot said toggle spoke members, bearing pins extending through ysaid hub and felly members and the ends of said In testimony whereof we have allixed our toggle links, springs interposed between signatures n presence of two witnesses.
